"I ask, sir, what is the militia? It is the whole people, except for few public officials." 

  -- George Mason --

According to the U.S. Constitution, Federal Law, nearly all state constitutions and state code, all male citizens ages 18-45 years are members of the militia. According to Anglo-Saxon Common Law, and the laws and customs of the American Colonies before our separation from the British Empire, all males (and even females during an actual emergency) between the ages of 16 and 60 were considered members of the militia. So the militia, like your God given rights, existed before the United States government was formed. And as such, you are already a member of the militia, by statute and by God-given right.
